14. The method of claim 13, further comprising: responsive to detecting an occurrence of the first target event during playback of the live video, prompting the user to initiate playback of the recorded video.

15. The method of claim 13, wherein the second target event comprises at least one of: one or both eyes of the user being opened; a head of the user being turned towards a field of view of a front-facing camera of the computing device; and the eyes of the user moving inside a field of view of the front-facing camera.

16. The method of claim 13, wherein the second target event is specified by the user.

17. The method of claim 11, further comprising: recording a video of the user with the selected at least one effect applied to the hair region of the user, wherein recording the video starts at a time instance when the first target event was detected; detecting an occurrence of a second target event relating to actions by the user; and responsive to the occurrence of the second target event, performing playback of the recorded video.

18. The method of claim 17, wherein the second target event comprises at least one of: manipulation of a playback control in the user interface; a gesture performed by the user sensed by a front-facing camera of the computing device; one or both eyes of the user being opened; a head of the user being turned towards a field of view of a front-facing camera of the computing device; and the eyes of the user moving inside a field of view of the front-facing camera.
